Usually typed in higher case to exemplify the yelling of the phrase, TROPHIES YO was a term coined by Hilden of the Drunken Gamers Radio podcast (also known as the Drunken Robotic Team Fremont of Panicked Gamers Live). Whenever one talks about trophies in regards to the PlayStation Network's achievement system, it is best to alter the utterance accordingly.

"And you can get gold, bronze or silver TROPHIES YO!!!!"
